    Hmmmm, how experienced are you with normal through-hole soldering are you?

    Somewhat. My wife has some background, too.

    Excellent. I'll try to design you a board using fritzing. It has a very simple one-click board ordering option, and is also free software.

    Surface mount soldering is a skill, but for components that you'll be using here is not a difficult one to learn if you can already solder.

    The main pieces of equipment you'll need are some appropriate tweezers and some good solder wick. I use regular 0.7 mm solder, but finer solder can be useful. Using a solder with a greater flux percentage will also help.

    Yeah, and I've been trying to find time to design the board for you. I've failed so far :-(

    So things are starting to slow down for me a bit. I was wondering if you could help me take a short cut haha. Hamblin, the researcher at Harvard who has discussed this with me over the past couple months, mentioned that THIS device is suitable for my purposes. The only problem is that it is meant to attach to a battery, but I'd like to plug it into a 120V wall wart. THIS is the wiring diagram for the device. Can you guide me to this end?
